Phil demonstrates the BHI NEIM1031 Noise Eliminating In-Line Module

Many thanks to SWLing Post contributor, Phil Brennan, who writes:

[Recently] one of your contributors mentioned that he purchased a BHI DSP unit at a discounted price. I purchased one (a different model to the one in the previous post) some months ago before I headed away travelling.

The post reminded me that I had made a small video demonstrating the DSP unit on my FRG7. The video shows me tuning the DSP on a broadcast of Voice of the People on 3912 khz. While QRM at my place isn’t too bad, it’s still present and the DSP does aid in clearing up a signal.

Voice of the People is usually jammed by the DPRK and the DSP also assists in reducing the roar of the jammer. Of course one can go to far with DSP and the audio can suffer from that underwater sound.

Thank you, Phil! The FRG-7 is an ideal receiver for something like the BHI module since it precedes on-board DSP. The great thing about an in-line module, of course, is that it can be used with a variety of receivers.

Dan offers services to digitally preserve off-air recordings on legacy formats

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

Some years ago, I urged those of us survivors in the shortwave listening  community to transfer any reel or cassette tapes to digital format. In recent years we have lost many top DX’ers to illness. Collections of recordings have unfortunately also been lost because family members are not able to preserve them or have no interest in doing so.

If any SWLing Post readers have such recordings, I am able to transfer them from/to to any format — including MD, SONY Microcassette (both of these are obviously still legacy formats but many still use MD for example), and straight to solid state media such as SD, MicroSD, etc

While I realize that most people do have the knowledge and capabilities to transfer old  recordings, I know many lack the time and patience to do so. So I am offering my services here, for reasonable fees to compensate for time invested. You can reach me at: dxace1@gmail.com

Those who wish to simply donate recordings can send them to me (please get in touch first).  Anyone who does wish to have their recording collection(s) transferred in full and to have  original tapes or cassettes returned, I ask to be compensated for postage costs. If you wish  to provide solid state media for the transfers that is fine, but please make sure that thumb drives  or memory cards are of sufficient size. Otherwise I will obtain memory cards/sticks and add this to the cost.

In recent years I have transferred recordings of about a dozen DX’ers who have passed, and for a few who left the hobby. All of these recordings are valuable as they represent snapshots of the SW broadcasting era and of history — they should be preserved.

I can certainly vouch for Dan and his integrity, so if you would like to have your recordings transferred, he’s the guy to do it. Thanks, Dan!

Many thanks to SWLing Post contributor, Mike Barraclough, who shares the following link from The Sunday Guardian Live via Facebook:

At present, AIR has only two Balochi speaking people who have been helping with the daily one-hour programme transmitted to Balochistan. A senior AIR official, on the condition of anonymity, said, “There has always been a dearth of Balochi speaking people here. Even before Balochistan got attention in mainstream Indian media, we had been working to improve our Balochi show. For years, we had been writing to the Ministry of Home Affairs and Ministry of External Affairs to help us get some talented people from Balochistan who can work with us on improving content in our Balochi shows. ”

[…]”Since we are gradually switching from short-wave to a web-based service now, all our overseas shows in various languages are already starting to get more human resource. We have more funds to invest on quality of our programmes. Earlier, such funds were largely spent on the maintenance of short-wave machinery.”[…]

Many thanks to SWLing Post contributor, Tom, who writes:

Even though I am not Catholic this news may interest you or others since once broadcast it will be a good piece of history if anyone wants to record it for the shortwave archive:

Indeed–thanks, Tom. It would be great to add a recording of this broadcast on the Shortwave Radio Audio Archive.

Tropical Band DXing at home with Elad FDM DUO and Wellbrook ALA1530 active loop

2-jungleRecently I have spent a little more time listening out for Tropical Band stations from my shack in Oxford UK, attempting to emulate some of the very nice signals I have previously recorded out on DX’peditions. The obvious problems with this (and they are numerous) include the relatively weak signal strength of many tropical band stations, the ubiquitous blanket of QRM, resulting in generally poor SNR, lack of space for a large antenna……need I go on?! Fortunately, the Elad FDM DUO has proven to be a very senstive and selective receiver, capable of, at times, incredible SNR, coupled with almost limitless signal conditioning options and SSB, SYNC, ECSS etc. Throw the Wellbrook ALA1530 active loop into the mix (not literally!) and you have a very powerful Tropical Band receive set-up. The Wellbrook is able to null most (although not all) QRM in my shack and that really can make the difference between simply observing a carrier and actually hearing audio. Clearly one cannot expect to hear DX at home under heavy QRM as well as you might outdoors, however, the following stations were logged in the past month or so, with respectable signals, with the ALA1530 indoors:
